Guide to Atmospherics

=Summary=

Atmospherics (or Atmosia) is the land of pipes and air, a peaceful place often left to its automatic work. To the untrained eye, it might appear to be entirely impenetrable and useless, just a mess of pipes that should be left alone to do their own work while the Atmospheric Technicians goof off in the break room. But this is far from the truth. In the hands of a competent technician, Atmosia can just as easily save the station as it can horribly destroy it. Also check out the Gas Turbine page to learn how to use it.

Content

Atmosherics contains several notable things that every Atmospheric Technician should know about:

• Atmospheric Alert Computer: This computer console will tell you where your attention is needed. A green indicator signals everything is alright, a yellow indicator signals something went wrong, and a red indicator means you should get your ass in gear and move out;

• Central Atmospherics Computer: From this computer, you have complete control of every air alarm on the station, allowing you to change vent, scrubber and mode options. By default, every air alarm has their remote access enabled, so you can theoretically do your job without ever leaving Atmosia, assuming you have competent Engineers;

• The Atmospheric Pipe System: This system takes in the station's waste air, filters it, and provides fresh air for everyone (except Vox and Plasmamen) to breathe;

• The Distribution Computers: These computers allow you to see how much of a certain gas you have in storage, in addition to letting you change the rate at which they output;

• The Gas Containment Areas: These are small, walled off areas containing large amounts of all gases. Vital for maintaining a breathable atmosphere aboard the station.

• Reserve Air Canisters: Extra canisters of air mix, oxygen, nitrogen and nitrous oxide that can be used to refill portable tanks, or as emergency reserves to fill rooms after a breach;

• Firefighting Equipment: Enables Atmospheric Technicians to survive easily for extended periods in difficult atmospheres. These include specialized firefighting armour and backpacks that fire metal foam;

• Atmospherics Hardsuit: This hardsuit is completely fireproof and can withstand raging plasma fires, in addition to, of course, freely allowing spacewalking (yes, you too can always be on fire and laugh it off);

• Portable Scrubbers / Portable Air Pumps: Allow you to quickly filter / repressurize (respectively) areas of the station;

• Portable Space Heaters: Can be used to keep an area from freezing;

• Pipe Dispensers: Allow repair / construction of disposal pipes, air pipes, supply / waste pipes and heat pipes;

• Fuel and Water Tanks: For use when fighting fires or other hazards;

• Freezers and Heater: Allow you to freeze or heat the gas in the pipes when routed through them;

The Pipes

For the following section, it would be best to think of air as a fluid since, technically, it behaves like one. Imagine it as being a current of water flowing through the pipes. Atmospherics is pretty simple, but the pipe layout makes it slightly confusing for the untrained eye. It consists of four pipe "loops", which are color-coded for easy checking:

• The dark blue loop is the Distribution Loop, or Distro Loop. It sends breathable air (roughly 80% nitrogen and 20% oxygen) to all the vents on the station, and is fed by the cyan loop lower down in Atmospherics;

• The cyan loop is responsible for creating Mixed Air to feed into the distribution loop;

• The red loop is the Waste Loop, which retrieves waste air from the various scrubbers on the station and feeds it to the Filtering Loop;

• The green loop is the Filtering Loop, which filters out the various gases in the waste air provided by the Waste Loop at various filters placed along it;

• The yellow loop is the Mix Loop, which is internal to Atmospherics and is used for custom air mixes. It is rarely used for anything not highly illegal

The air breathed by humans on the Cyberiad is made out of oxygen and nitrogen, and is mixed on the south end of Atmosia (in the cyan pipes). The gases are pumped from their containment areas and into the air mix containment. The breathable gas is then pumped through the cyan loop to the north of Atmosia, where it is then pumped into the blue loop and out to the station.

The filtering loop runs the gases through the filters along the green piping and is your main tool in fighting gas spills and large fires.

The "canisters" of the station's Atmospherics network are actually rooms filled with the appropriate gas. The output of these rooms are controlled by their respective supply control computers and a small valve that allows the gas to be injected into the pipes.

The Gases

• N2: One of the components of the air mix. N2 soaks up heat in the air, and lowers the temperature of a fire. By association, it can very quickly lower the temperature of a fiery rupture to the point where the flames self-extinguish.

• O2: You breathe this. Running out of O2 will cause your slow death by suffocation damage. It is also required for a fire to even start, and hold, ending the fire when the O2 or plasma is depleted. Having less than 16 kPa of O2 flowing into your lungs chokes you.

• Air: The gas mix that is distributed in the station. It is composed of 70% N2 and 30% O2.

• CO2: An invisible, heavy gas, CO2 is one of the first and fastest gases the scrubbers suck out of the air. It chokes people effectively and quickly, and if you can be bothered to set the alarms up, will result in a invisible room that kills those in it. Takes some setup and can be very, very annoying. The emote for this at below incapacitating levels is gasping and choking.

• N2O: A white-flecked gas. Makes you laugh at low doses and at higher ones puts you to sleep. Scrubbers don't deal with it too well and portable scrubbers just choke on it. If using this as a sleep gas mix do *not* forget the O2 at at least 16 kPa, or you will kill someone.

• Plasma: The one truly flammable gas on the station, plasma is purple, and highly toxic. Of note is the fact that in the presence of any oxygen at high pressures, plasma pumped into air can and will spontaneously ignite on turf at high pressures.

Setting Up Atmospherics

In it's default state, Atmosia can technically handle most atmospheric crisis, albeit highly inefficiently. Experienced technicians can play with it at will, re-routing the pipes and adding all sorts of machinery to make it more efficient. This, however, requires a lot of experience with the role, and a guide on all possible Atmospherics configurations would probably require a small wiki of its own.

As such, it's important that you understand how exactly gases work, and how they flow from one place to another. Take your time to become acquainted with the Atmospherics layout, and try and wait for a few crisis before attempting any major redesign projects. However, here are some important things to keep in mind:

• Hotter Gas is under Higher Pressure - The hotter a gas is, the more pressure it exerts on the piping. This means that a single room's amount of gas, if properly heated up, can be the equivalent of half the station's atmosphere in pressure alone. This becomes problematic if you're using pressure pumps, since they only go so far. In addition, the filters on the filtering loop work on pressure as well, so keeping gas cool and low-pressure is incredibly important.

• Volume Pumps are Far Better - Pressure pumps are, by and large, useless in dealing with waste air when compared with volume pumps. Pressure pumps should be used for projects that require very specific amounts of gases to be pumped, such as some Turbine setups. Volume pumps bypass this by ignoring pressure and instead moving volume of gas. Seeing as the gases' volume remains constant inside the pipes, this translates into a faster waste loop.

• Less is More, does not apply - At least for pumps. While you do still have limited room to work with, three volume pumps will always work better than one. Just remember to keep the number of pump clusters constant: you don't want three pumps feeding a single one, bottlenecking the whole thing.

• Space is Cold, and so is Gas - Aside from the freezers, which are very inefficient if not upgraded, there are two main ways of cooling down gas (which is useful when handling fires, as it reduces pressure and helps it clear out faster): the space loop and heat exchange pipes. Routing a gas through the space loop will cool it down to the temperature of the vacuum outside (a chilly 21 Kelvin), quickly and efficiently. Heat exchange is a bit more complicated, however. It works by having one of set of exchangers have pre-cooled gas (either via freezers or space loop), and having another set of exchangers adjacent to the first one. Any gas that flows through the second group will transfer its heat to the pre-cooled gas, also quickly and efficiently.

• Round and Round and Round it goes - It's perfectly possible for you to just send gas back into the space loop. Having T-valves set up to create tiny loops is a great way of further cooling down gases and setting up buffer zones to keep gases rolling without clogging up the filtering loop. This is especially useful in the case of fires and large spills, where you must reduce the waste air's pressure as much as possible in order not to clog the various air filters.

Air Alarm

An Air Alarm is the main method of control over the Cyberiad's Atmospheric System. They enable you to control the vents and scrubbers in rooms, as well as any other Atmospherics Equipment, in addition to accessing a multitude of options regarding Atmospherics duty.

There is an Air Alarm located in each individual room on the station, in addition to larger, open areas (such as Medbay or the Primary Hallways). Where exactly the Air Alarm is in the room does not matter; so long as it is withing the confines of the room, and the room itself is powered, it will allow you to control the room's atmospherics.

Portable/Rapid Pipe Dispenser

File:Rapdid pipe dispenser.png

There are a few different pipes and devices that you can get from the portable or rapid part dispenser.

Pipes

Items	Name	Description
	Atmospheric Pipes	These are simple pipes that is normally found all around atmospheric.
	Air Supply Pipe	Used to distribute air all across the station.
	Scrubber Pipe	used to move waste or harmful gases.
	Heat Exchange Pipe	Allow you to cool / heat gases based on the ambient temperature of the tile they're on. Think space loop (for cooling) or the Toxins burn chamber (for heating)

Devices

Items	Name	Description
	Unary Vent	Once placed down it will have to be turned on by activating it at the room's air alarm
	Passive Vent	An air vent that releases pressure if connected to a atmospheric pipe.
	Dual-Port Air Vent	Has a valve and pump attached to it. There are two ports
	Air Scrubber	Self explanatory, scrubs the nasty out of things, or acts like a vacuum. Like vents, needs to be turned on by an air alarm after being put in place
	Connector Port	Used to attach canisters, pumps or scrubbers to a pipe network. If you can't get a pipe network easily to the filter loop, an empty canister can be a good substitute
	Gas Pump	The basic pumps you'll find all over Atmospherics. Good for precise pressure levels. Goes up to 4500 kPa
	Volume Pump	A bit like the pressure pump, but pumps via volume rather than going for pressure. 200 is its max output, but this is fairly significant. Faster than a pressure pump (You can even fill canisters up past the standard 4500 kPa pressure!), so best used in systems where a specific maximum pressure isn't needed, such as the waste loop
	Passive Gate	Think of it as a one-way manual valve, but electronic. Doesn't pump gas, but lets a certain amount of pressure through. Can be set up to 4500 kPa. It should be noted that its power status light can be easy to miss, being just a small red / green light
	Gas Filter	Checks for whatever gas you set it to, then filters it out into another pipe
	Gas Mixer	Like a filter, but mixes gasses instead of filters. There is one in Atmospherics that mixes nitrogen and oxygen
	Air Injector	Used to inject air at a typical value of 50 liters a second. Mostly seen in combustion chambers.
	Manual Valve	A manually-controlled valve, it requires no power and also no ID authorisation to use. Is arguably better over the digital valve in pipe-networks with possibilities of massive destruction due to the need of ID access on the digital valve. Displays a small green light when open.
	Digital Valve	An electronically-controlled gas valve. It uses the station-grid's power to be operated but requires sufficient ID access to be allowed use. Displays a small green light when open.
	Meter	Want to know how much gas is in a pipe? Use these
	Gas Sensor	Used to sense the pressure and temperature of the gas surrounding the sensor itself, rather than a pipe.

Disposal Pipe

Items	Name	Description
	Disposal Pipe	Those pipes are made through the disposal pipe dispenser, use them to fix or expand to the disposal system of the Exodus.
	Disposal Bin	Where people put their trash which are then sent to the disposal area via the disposal pipe system.
	Disposal Outlet	Whenever someone or something has reached this from a disposal pipe, they are thrown out at quite a fair speed and typically end up hitting a wall before stopping.
	Disposal Intake	If something's been thrown into the intake, it will take it and put it into the attached disposal pipe, sending it off on it's merry way.

In addition to handling the station's Atmosphere, a secondary job you share with the Engineers is making sure the Disposals network is functioning properly.

Seeing as these don't actually handle anything, it's literally as simple as drawing lines from point A to point B.

That said, it's still possible to create truly dizzying contraptions with the use of outlets and pipes, such as quick travel "highways" in the Central Primary Hallway.

Traitor Atmos: Horrible Deaths Ensue

There is precisely one occasion where large scale Atmos sabotage is permitted: the hijack objective. In any other condition, sabotaging the station in any large scale will result in the staff getting very annoyed, so unless you have it ADMINHELP BEFORE TRYING ANYTHING BIG.

With that said, wreaking havoc with Atmosia is as easy as hooking up the plasma / carbon dioxide / nitrous oxide containment areas (or an unholy combination of all three) to the main Distribution Loop, then remotely replacing the air on the station's Air Alarms. Slowly, but surely, death ensues.

If, however, misery may not be global, you have a variety of tools at your disposal. Your AXE can very easily murder anyone if dual-handed, you have Engineering right next door, and Atmospherics itself is out of the way and rarely looked at. In addition, you're the one closest to the AI Minisatellite. Use that advantage wisely.

The Supermatter: Time to Shine, Baby

The Supermatter Engine is perhaps the epitome of Atmospheric excellence. It represents a beautiful, pseudo-scientific amalgamation of Engineering and Atmospheric work, and can be used for truly astounding effect.

While Engineering concerns itself with constructing the Supermatter's containment area and emergency disposal system, you'll be the one responsible for constructing the system that will scrub out the waste plasma produced, and supply fresh coolant to keep the Shard from delaminating. This is the single most important component of the Supermatter Engine, and a well-designed cooling system can allow for continuous emitter fire without so much as a minor hiccup. This can snowball into absolutely ridiculous amounts of power.

In addition, you can also cool down plasma for use in radiation collectors. The colder the plasma, the more you can fit into a plasma tank, and the more power it will generate!
